Making of America, is a digital library project of the University of Michigan and Cornell University
Mall of America, the United States' largest mall located in Bloomington, Minnesota
SM Mall of Asia in the Philippines
Mechanism of action, the means by which a drug exerts its biological effects
Memorandum of Agreement
Microlensing Observations in Astrophysics group. A group of astrophysicists using gravitational lensing in hopes of finding exoplanets
Military operations area, an area where United States military activity takes place
Minute of arc, a unit of firearm accuracy

Now that you know what motor oil is, how it is made and what it does, here comes the most confusing part of all: grades. In order for motor oil to perform its major function - lubrication - its viscosity (the measure of it's thickness or resistance to flow) must be capable of holding up under your engine's extreme temperature conditions. Oil thins when heated and thickens when cooled. Choosing the proper viscosity grade for the ambient temperature of your geographic location becomes vitally important.
